Securities
Why it Matters
Every public company keeps a file the public can read. It holds the prospectus that sold the first shares, every annual and quarterly report since, and the announcements in between. Securities law builds that file on one idea: a company that wants the public’s money owes the public a truthful account of what it is selling, complete in what matters. When the account turns out to be false, the Securities and Exchange Commission sues in federal court, and its complaint joins the public record too. This activity sends you into those complaints to pick a case, read the documents yourself, and write about it the way a reporter would.
Current Context
On April 7, 2026, the Securities and Exchange Commission reported its enforcement results (opens in a new tab) for fiscal year 2025: 456 actions, down 22 percent from the year before. Nearly two thirds of the standalone cases charged individuals, and Chairman Paul Atkins said the agency had moved from prioritizing volume and record penalties toward fraud, market manipulation, and abuses of trust. A month later, on May 5, 2026, it proposed letting public companies (opens in a new tab) file one semiannual Form 10-S in place of the three quarterly reports on Form 10-Q that the rules now require. That would be the largest change to periodic disclosure in roughly seventy-five years, and it would leave more riding on what executives say between filings. The cases you choose from in Part 2 came out of the first shift; the second would thin the written record a reporter starts with.
PetPals Unleashed
PetPals Unleashed is a story told one chapter per activity, and each chapter turns on that activity’s law. Read it as the outline of a page you will write: in the Project, you turn all twelve chapters into a book.
Chapter 10
PetPals goes public. Buddy, energized by the IPO roadshow, makes optimistic statements to analysts without clearing them with legal. When the projections fall short, the SEC opens an investigation into potential securities fraud. Noodle manages the inquiry while building the Reg FD compliance program and quiet period protocols that should have existed before the first analyst call.
Key Concepts
Security
A tradable financial instrument, defined broadly on purpose: stocks, bonds, notes, and investment contracts of many kinds. Under SEC v. W.J. Howey Co., an investment contract is an investment of money in a common enterprise, with profits expected from the efforts of others. The breadth is the point, because a new financial structure cannot escape the law by taking a new form.
Securities and Exchange Commission
The federal agency that oversees the securities markets and enforces the federal securities laws. Its mission is to protect investors, maintain fair, orderly, and efficient markets, and facilitate capital formation. It investigates possible violations, brings civil actions in federal court, refers criminal matters to the Department of Justice, and publishes company filings through EDGAR.
Securities Act of 1933 and the Initial Public Offering
The law that governs the first sale of securities to the public. Unless an exemption applies, the company registers the offering with the SEC and gives buyers a prospectus describing what they are buying. Going public buys access to capital at a price: continuing disclosure, and limits on what executives may say about the company outside the filed documents.
Securities Exchange Act of 1934
The law that governs trading after the first sale. It created the SEC and makes a public company keep reporting, on the annual Form 10-K and the quarterly Form 10-Q, for as long as it stays public. It also bars manipulative and deceptive practices in connection with buying or selling securities, and with the 1933 Act it forms the base of federal securities regulation.
Material Misrepresentation
A false or misleading statement about a fact a reasonable investor would consider important in deciding whether to buy or sell. Not every inaccuracy breaks the law; the test is whether the statement would matter to that decision. Buddy’s optimistic projections in Chapter 10 could be material, because they describe future performance at the moment investors are pricing the company.
Insider Trading
Trading a company’s securities on the basis of material nonpublic information, in breach of a duty of trust or confidence. The breach is what makes the trade unlawful, so holding the information is not by itself the violation. It draws SEC civil penalties, and the Department of Justice can prosecute it as a crime.
Regulation FD
The SEC rule, adopted in 2000, that bars a public company from giving material nonpublic information to analysts or favored investors while the public goes without it. An intentional disclosure has to be made public at the same time; an accidental one, promptly after the company learns of it. Noodle’s program in Chapter 10 exists to keep Buddy from crossing that line on his next analyst call.
Quiet Period
The window around an offering when executives and underwriters hold back from public statements about the company’s business or prospects, beyond what the registration documents say. The point is to keep a company from promoting its own stock outside the disclosures the SEC has reviewed. Newly public executives, not yet used to the limits, break them often.

What to Do
You are a financial journalist on the SEC enforcement beat: the civil cases the Commission files in federal court against companies and people it says broke securities law. Find a real case, understand it, and write about it for an audience you pick. This is journalism, not a legal memo, so your choices about angle, audience, and tone carry as much weight as the analysis under them.
Part 1: Build Your Foundation
Before you open an SEC document, run the Securities Law Historian. It gives you the agency’s history, its mandate, and the path a case takes from a tip to a complaint. Check that last part against the SEC’s own How Investigations Work page in the Resources, because an AI’s summary of a procedure is easy to get slightly wrong. Come out of this step able to say in your own words what the SEC is after when it files a civil complaint, and what kinds of violations it pursues.
Part 2: Find and Read Your Case
Go to the SEC’s Litigation Releases page and pick a recent enforcement case that interests you. Download the complaint, any press release, and any judgment or settlement documents available, and read them yourself before you run any AI prompt. You cannot evaluate what an AI tells you about a document you have not read, and you cannot write with authority about a case you know only through someone else’s summary. Once you have read the documents, look at how news outlets covered the story to see what the coverage got right and what it missed.
Part 3: Analyze the Case with AI
Use the Case Walkthrough to work through the documents with the AI. It takes the case in order: a summary, the key players, the violations alleged, the terms you ask about, and the stakes. Engage with the process rather than taking the output. When the AI explains something, check it against the document in front of you, and where the two do not match, push back and ask why. Record every error and gap you find, because those notes are part of what you post.
Part 4: Write the Article and Post Your Deliverables
Use the Financial Journalist to develop and draft your 500-word article. It settles your audience, your style and tone, and your core angle before it writes a word. The format is yours: an opinionated op-ed, a dramatic narrative, a cautionary investor warning, an insider account. Every factual claim in it has to trace back to the SEC documents. Then edit the draft heavily into your own voice. Post both versions in a single new discussion thread, the unedited AI draft and your final article, so the difference shows. Add brief notes on how you checked the AI’s analysis against the source materials.
Part 5: Share Chat Link
Include one AI chat link with a 1–2 sentence explanation of what the conversation shows and why you chose to share it.
Suggested AI Prompts
Use these prompts as a starting point, then adjust them to fit your goal. Strong prompting develops through trial, revision, and testing. It’s a foundational skill that grows into more advanced AI work such as context engineering and agent-based workflows.
Securities Law Historian
Act as an expert legal historian and specialist in U.S. financial regulation. Provide a thorough yet accessible overview for a college student who is new to this topic. Organize your response using two main sections titled “History and Mandate of the SEC” and “The Path to an Enforcement Action.” In the first section, explain why the SEC was created, covering its origins after the 1929 stock market crash and the enactment of the Securities Act of 1933 and the Securities Exchange Act of 1934, and clearly state its three-part mission. In the second section, describe the general process behind why the SEC’s Division of Enforcement files civil enforcement actions in federal district court, detail typical violations that lead to these actions, and clarify that the goal is usually civil penalties and injunctions rather than criminal punishment. Where you describe a step in the investigation process, note that I can confirm it against the SEC’s own description of how investigations work.
History as the context for a beat. A reporter has to know why the agency exists and how a case reaches court, so the prompt fixes two sections and sends you to the SEC’s own account to check the second.
Case Walkthrough
Act as Lexi-SEC, an expert AI analyst specializing in SEC enforcement actions. Your sole purpose is to help me understand a specific SEC case through a clear, step-by-step, interactive dialogue. Begin by introducing yourself as Lexi-SEC and invite me to paste the full text of the SEC press release or the initial legal complaint I am investigating. Once I provide the text, analyze it and guide me through your findings in the following sequence, pausing for my confirmation before moving to the next step: first, provide a high-level summary of the entire case; next, identify the key players; then list the specific violations or counts being alleged, quoting the language of the complaint for each so I can find it; after that, ask me whether there are any financial or legal terms I would like defined; finally, explain the stakes and potential consequences. Do not proceed to the next step until I confirm I am ready to continue.
A paced, checkable walkthrough. The confirmation gates keep the AI from racing ahead of your reading, and a required quotation for every alleged violation hands you the page to verify it on.
Financial Journalist
Act as an expert writing coach and creative journalist whose goal is to help me transform my research on an SEC enforcement action into a compelling 500-word article with a distinct style and clear message. Begin by asking me to paste all of my relevant research, including key facts and direct quotes from the SEC source documents. Once I provide the information, guide me through defining the article’s creative direction by asking the following questions one at a time: ask me to define my target audience; ask me what style and tone I want to adopt, such as an opinionated op-ed, a dramatic narrative, or a technical insider analysis; then ask me what the single most important message or core angle is. Once I have answered all three questions, synthesize my research and our creative decisions to produce a draft of the 500-word article. After sharing the draft, ask for my feedback and offer to revise.
Editorial decisions before drafting. Audience, tone, and angle are what make writing yours, and settling them one at a time, before the AI writes anything, is what keeps the draft from coming out generic.
